Continuity mistake: Dan is shot at chest height in the previous episode. In this episode the gunshot is to the head. (00:04:20)
Visible crew/equipment: When David is talking to his daughter, just after the remark about there being nothing to worry about, a camera moves into shot on the right hand side of the screen. (00:08:50)
Revealing mistake: When Dan is shot at the end, you can see protective equipment under his shirt as he falls back. (00:40:40)
Continuity mistake: When Alan tells Teri he will stay with her until they find Kim, Teri's bag strap falls off her shoulder. Camera changes and the strap is back up on her shoulder. (00:32:30)
Continuity mistake: When Teri is talking to Alan about Kim failing Algebra, she has her hand on her bag in one shot and on her coffee in the next. (00:31:40)
Continuity mistake: When Alan gets out the car to ask the cop to speed things up his car door is open or closed depending on the shot. (00:15:15)
Visible crew/equipment: As Kim runs over to her friend at the end, a camera shadow can be seen on her arm. (00:41:00)
Continuity mistake: When Richard is shot and on the floor, there is a blood blob above his shirt pocket that keeps disappearing and reappearing. (00:35:10)
12:00 Midnight-1:00 A.M. - S1-E1
Audio problem: When we see the timer for the bomb on the plane, you hear the beep to indicate each second it clicks down. However, we see the timer say 24 seconds. We hear several beeps and 7 seconds later the timer says 20 seconds. The key point of the program being real time, so the timer should be on 17 at least. (00:37:30)
11:00 P.M.-12:00 Midnight - S1-E24
Other mistake: Mason asks Nina the ETA on the tactical teams, to which she responds "Five on the Alpha, Eight on the Beta." There's a timecheck 3 minutes later, and after the break they still haven't arrived. Team Alpha continues to be more and more late than estimated. Jack begins to break into a van, still no tactical team has arrived. Jack kills Victor Drazen at the 17:47 time check, still no back up. They finally show up at around the 31 minute mark. (00:08:00 - 00:21:15)
Revealing mistake: Tony Almeida tries to phone with a telephone, which is not switched on. You see that the screen isn't displaying any information. (00:25:10)
12:00 Midnight-1:00 A.M. - S1-E1
Continuity mistake: Kim Bauer has a full set of glittery pink disco nails on episode one (midnight) but then these are not visible at all in most episodes. In the 2pm episode her nails look clean/natural in nearly all the shots, apart from during the phone call with Rick where traces of pink glitter can be seen. I know she's had a very rough night but it doesn't explain the amount of damage her nails have sustained.
12:00 Midnight-1:00 A.M. - S1-E1
Character mistake: When Jack subdues Mason he proceeds to check his pulse to check Mason is still alive. When taking the pulse however Jack uses his thumb. This is not how a pulse is checked, as the thumb has it's own pulse and would therefore give Jack's pulse instead of Mason's. Being ex-Delta Jack would know this and not make the simple mistake. (00:22:10)
11:00 A.M.-12:00 Noon - S1-E12
Character mistake: When Jack mentions the siege at Waco, he implies that the ATF's raid failed because an agent on-site screwed up. Their plan had actually been shot before the assault team even reached the compound; a reporter inadvertently compromised their advantage of surprise when he got lost and asked David Koresh's brother-in-law for directions, providing the Branch Davidians ample time to arm themselves in anticipation of self-defense.
11:00 P.M.-12:00 Midnight - S1-E24
Other mistake: As David is walking away from Sherry, there is daylight flooding into the ballroom, just 20 minutes before midnight. (00:32:30)
Audio problem: When Jack is getting suited up, the new bloke arrives and we hear him put his case down on the glass desk. Camera changes and we see him put the case down on the desk a second time. (00:12:50)
Suggested correction: You can see George (replacement to Alberta) holding 2 briefcases just before Jack sits down to put his shoes on.
